CERAMIFICATION (CERAMIZATION)CHARACTERISTICS
A process leading to transformation from viscoelastic polymer composite to continuous, rigid ceramic structure, during exposition of the composite on fire or elevated temperature.
Before ceramification:• Good processability• Plsticity/elasticity• Easy to colour• Combustibility• Low thermal stability
After ceramification:•incombustibility•Stiff•Porous (thermal insulation)•Thermally stable
